Question

GIVING BRAINLY AND 20 POINTS

A sound wave in air has the wavelength of 1.36 m. Calculate its frequency? Assume the speed is 340 m/s.

Answer 1

Answer: the answer is 0.074Hz

Explanation:

Given, (In air)

Velocity V=340m/s

Frequency f=20,000Hz

Wavelegth λ=?

V=f.λ

λ=

F

V

​

=

20,000

340

​

=0.017Hz

Also, Given (in Water)

Velocity, V=1480m/s

Frequencyf=20,000Hz

wavelength, λ=?

V=F.λ

λ=

F

V

​

=

20,000

1480

=​0.074Hz

Answer 2

Answer:

frequency

Explanation:

frequency is velocity/ wavelength

340/1.36

250
